Loudspeaker control and temperature measurement integrate device

The utility model provides a loudspeaker control and temperature measurement integrate device, includes wave filter, adder, power amplifier, extraction resistance, electric current and voltage filtering ware, electric current and voltage integrating meter ware and the logic unit that counts. The wave filter is received incoming signal and is formed output signal, and the adder forms the sum signal, forms the extraction signal through extraction resistance and sends sound signal for miniature speaker to form the hot voltage signal of coil, the electric current wave filter captures out the filtering current signal in extracting the signal, and the voltage filtering ware captures out filtering voltage signal by the hot voltage signal of coil, and filtering current signal and filtering voltagesignal are respectively through obtaining temperature signal behind the total mark logical product. 种扬声器控制与测温的整合装置，包括滤波器、加法器、功率放大器、萃取电阻、电流及电压滤波器、电流及电压积分器以及算数逻辑单元。滤波器接收输入信号并形成输出信号，加法器形成相加信号，经萃取电阻形成萃取信号以供微型扬声器发出声音信号，并形成线圈热电压信号
